Post subject:  SSD Recovery challenges -- MCU not supported
Dear Friends
Indian market is been flooded by cheap chinese SSD brands like EVM / Nforce etc.
Even branded SSD's like WD green are having MCU not supported in portable yet.
What guru's and super guru's do in such cases ? Are all non supported cases non recoverable or still proprietory secret tools exists which can do miracles. (( I will be happy to know particularly how arvika gives justice to such cases ))
Here is video of such SSD.
At the onset I do not own PC 3000 portable ,I have outsourced it to one of my friend. I don't have technical skills to delve deeper into nand world as well . This query is just to properly report customer for availability of solutions and keep myself updated with technology.

Drive from video give access to sectors. So not bad case. As you can see SMART is bad so it means that memory chips are degraded. Probably it could be corelated with FW issue. But for this particular case I think there is chance for recovery.

Thank you so much arvika
This SSD is hardly 2-3 months old , lower grade nand chips might be the reason of early degradation (though 500 TBW is been given) . Here is snap of the SSD

The MAS0902A is the most data recovery practitioner-friendly of the cheap controllers in my opinion, and most of the time, damaged drives allow you to access logical sectors. Instead of fatal firmware corruption. Although PC3000 SSD does not support it yet, most cases can be restored by DE clone

Thanks csava
yes we tried to reverse clone in DE ,but controller restarts continuously so couldn't succeed.

Can you adjust the NAND Vcc in-circuit?

In-circuit recovery of SSDs with "weak" NAND:

What a comprehsive R & D done by fzabkar , appreciate your technical expertise. I am doubtful we will be able to make changes in voltage due to insufficient experise in electronics. :good: :-D
